my environment: centos 6.3, qemu 1.5(source code build), libvirt libvirt-0.10.2-18.el6_4.2.x86_64.selinux enforce .
i have 2 questions
1.snapshot. permisson deny.
<seclabel type='dynamic' model='selinux' relabel='yes'>
[root ovirtdev images]# ls -lZ
-rw-r--r--. qemu qemu system_u:object_r:virt_image_t:s0 test.qcow2
image does not have the same MLS?
it does not seem like a selinux problem, because selinix does not record this deny.
May 27 09:48:49 ovirtdev NetworkManager: <warn> /sys/devices/virtual/n!
et/vnet0: couldn't determine device driver; ignoring...
[root ovirtdev images]# brctl show
bridge name bridge id STP enabled interfaces
ovirtmgmt 8000.000c290a2351 no eth0
what is the reason? does it matter with libvirt?
